Effect on the counting statistics over the detector of appropriate masking of non-Poissonian and multiple pixels. The distribution of the variance over the mean counts per pixel, measured pixel by pixel for 256 images of silicone oil. Masks 0, 1 and 2 correspond, respectively, to masking only the pixels flagged by DECTRIS, masking also the rebinned pixels between sub-modules and detector edges, and masking also pixels with high σ/[\sqrt{\rm mean}] (typically damaged pixels) as well as dilating by 1 pixel the regions around each masked pixel. The percentages of pixels masked in each case were 8.6%, 15.4% and 15.8%, respectively. The blue lines are a Gaussian fit to the final (mask 2) data and the difference curve. Inset: the same data on a semi-log scale. Reproduced with permission from Vaughan et al. (2025BB102) under a Creative Commons Attribution (CC-BY) Licence.
